Fine leads for paper and drawing board. Easy refilling with "12 in one go" for Mars micro, graphite 760, graphite 771, and graphite 779. Features a smoothly gliding lead for a rich stroke. Exceptionally elastic - particularly break-resistant. Good erasability. Marked with ISO color codes. Compatible with all mechanical pencils. Available in up to 7 degrees of hardness and 5 line widths: 0.3 mm, 0.5 mm, 0.7 mm, 0.9 mm, and 1.3 mm.

12 in one go: The lead container simply snaps on, allowing the entire contents to be filled into the Mars micro, graphite 760, and graphite 779 mechanical pencils at once.

Advantages:

• No handling of the lead.
• Lead does not fall out.
• Lead does not break.

ISO color codes: The identical color coding for mechanical pencils, fine leads, and ink pens facilitates the visual identification of line widths.

Environmentally efficient: STAEDTLER operates both ecologically and efficiently!

Efficient and environmentally friendly - that’s the idea! In our unique manufacturing process without PVC and plasticizers, over 90% natural raw materials are used. The elastic lead ensures high break resistance. The leads can be easily refilled with "12 in one go" for Mars micro, graphite 779, and graphite 760.
